Adjusting the Gamma setting

Gamma is the difference in contrast between the light tones and dark tones of an image. Any change you make in the Gamma level only affects the midtones of the image.

To change the Gamma level of the image, move the Gamma slider left or right, or type a value in the text box.

You can set a value in the range of 50 to 500 for Gamma.

Note:

See "Image controls button" on page 4-23 for full details on adjusting the gamma level.

Applying a preset tone curve

You can adjust the contrast within an image more finely by applying one of the preset tone curves. This allows more control over the image addition to using the Auto Exposure settings in the Image Controls dialog box. The tone correction list in the Tone Correction dialog box provides the six most common tone correction curves.

Note:

See "Using the tone curve" on pages 2-11 and 4-26 for details on tone correction.

Adjusting the Gray Balance Intensity setting

Gray balance makes it possible to remove a color cast (tinting) from a specific color.

(41)

1. In the Color Adjustment dialog box, click the button under Gray Balance Intensity.

This causes the pointer to change to an eyedropper located within the image in the Preview window.

2. Move the eyedropper pointer to the location that contains the color whose gray balance intensity you want to adjust, and then click.

3. To change the gray balance intensity level of the color you selected, move the slider left or right, or type a value in the text box.

You can set a value in the range of 0 to 100. Changing the value causes the color in the right hand box to change accordingly.

Your changes are also reflected in the image in the Preview window.

Note:

See "Color adjustment button" on page 4-28 for full details on adjusting the gray balance intensity level.

Adjusting the Saturation setting

Saturation is the density of a color. Higher density makes the color appear richer, while lower density makes it appear paler.

To change the saturation level of the image, move the Saturation slider left or right, or input a value in the text box.

You can set a value in the range of -100 (lowest color density) to 100 (highest color density) for saturation.

(42)

Note:

See "Color adjustment button" on page 4-28 for full details on adjusting the saturation level.

Using the tone curve

The tone curve provides you with a versatile means for adjusting the intensity of the colors of the image being scanned. You can adjust the shadow, midtone, and highlight values, which helps to ensure well-balanced coloring of the image.

Note:

❏ Use of the tone curve is recommended for fine adjustments after you have previewed the image and adjusted the highlights and the shadows using Auto Exposure and the Image Controls dialog box.

Use of the tone curve to make initial settings is not recommended.

❏ The button becomes unavailable whenever Black & White is selected as the Pixel Depth and None is selected as the Halftone.

The tone curve is located in the Tone Correction dialog box, which appears when you click the button in the Preview window. How to use each of the controls in the Tone Correction dialog box is described below.

2 Optimizing OCR Scanning

This section gives you suggestions and recommended settings in order to improve OCR (optical character recognition) scanning results.

Scanning text

Follow the steps under "Scanning an Image" on page 2-4 to scan the text. Make sure you select OCR for both Image Type and Destination in the EPSON TWAIN Pro dialog box.

If the recognition rate is not compatible with the default settings, follow these steps:

Improving character recognition

1. In the EPSON TWAIN Pro dialog box, make sure OCR is selected in both the Image Type and Destination list boxes.

Then click the Image Type button. This causes the Image Type dialog box to appear.

2. In the Image Type dialog box, select None for B/W Option, and then click OK.

3. In the EPSON TWAIN Pro dialog box, click Preview. Then click the button to display the Image Controls dialog box.

4. Use the Threshold slider to change the threshold value, monitoring the results of your changes on the Preview window. Increasing the threshold value makes characters thicker and easier to recognize.

5. If you still have problems, try using the enhancement tools in your OCR software to make adjustments and improve recognition.

(47)

Potential text recognition problems

The quality of the text in your original document greatly effects OCR results.

The following types of originals can make recognition difficult and should be avoided if possible:

❏ Copies of copies

❏ Faxes

❏ Text with tightly-spaced characters or line pitch

❏ Text that is in tables or underlined

❏ Cursive or italic fonts, and font sizes less than 8 points Remember that OCR software cannot recognize handwritten characters.

3-2 Using the Start Button

Scanning by Pressing the Start Button

The Start Button feature allows you to scan and send data to a target application with a single push of your scanner’s Start button.

You can open EPSON TWAIN Pro, start scanning, and have the scanned image sent to a certain application, simply by pressing the Start button on your scanner. To use this feature, you need to install Presto! PageManager for EPSON (hereafter,

"PageManager"), or other compatible software.

For installing PageManager, refer to Chapter 1.

When the Start button of the scanner is pressed:

❏ Windows 98, (or EPSON Scanner Monitor software on an operating system other than Windows 98), detects when the Start button is pressed and sends information to the

application, such as PageManager.

❏ The application will automatically open EPSON TWAIN Pro, scan the image and display it.

Note:

❏ You need to configure the Start button to launch the desired application before using this feature.

❏ The scanned image will be handled by the software to its maximum capability. For example, using PageManager, you can send the scanned image to a printer, or convert your scanned OCR image to text format and paste it in a word processing application--all by simply pressing the Start button.

❏ If the scanner is connected to a PC which is running EPSON Scan Server, the start button feature mentioned above is disabled. For information on using the start button in a networked environment, refer to the EPSON Scan Server & EPSON TWAIN Pro Network User’s Guide.
